Select the correct word to complete the sentence meaningfully:\n\n"If you write a forty page essay in one night, you will accomplish a huge _______."

Introduction / Context:
This vocabulary question asks you to select the word that best completes the sentence in a way that matches both the context and the collocation. The sentence talks about writing a forty page essay in one night, which is clearly a demanding task. The blank should therefore be filled with a word that conveys the idea of a remarkable achievement rather than something unrelated like a vehicle group or a type of sound.

Given Data / Assumptions:

• Sentence: If you write a forty page essay in one night, you will accomplish a huge _______.
• The action is difficult and impressive.
• Options: treat, feat, fleet, beat.
• We assume that the speaker wants to praise the scale of the achievement.

Concept / Approach:
The noun feat means a very impressive act or achievement that requires great courage, skill, or strength. This fits perfectly with the idea of completing a long essay in a single night. Treat usually refers to something that gives pleasure, such as a pleasant surprise or special food. Fleet refers to a group of vehicles or ships. Beat as a noun refers to rhythm or a journalist's assigned area. None of these match the intended meaning in this context, so feat is the correct choice.

Step-by-Step Solution:
Step 1: Focus on the phrase accomplish a huge, which suggests a significant achievement. Step 2: Recall the meaning of feat as an impressive or difficult achievement. Step 3: Insert feat into the sentence: you will accomplish a huge feat, which sounds natural and appropriate. Step 4: Check that the other options do not fit the sense of achievement in this context.

Verification / Alternative check:
Try each option in place of the blank. Accomplish a huge treat does not work because we do not usually accomplish a treat. Accomplish a huge fleet is meaningless because fleet is not an achievement. Accomplish a huge beat does not capture the idea of success either. Only accomplish a huge feat accurately conveys that writing the essay is a difficult and notable achievement.

Why Other Options Are Wrong:
Option A, treat, is associated with giving pleasure, not with performing a challenging task. Option C, fleet, refers to a group of vehicles or ships and has nothing to do with completing work. Option D, beat, is used for rhythm or sometimes in slang, but not in the formal sense of a major achievement in this sentence. Therefore, these options are semantically inappropriate.

Common Pitfalls:
Learners may confuse feat and treat because they sound similar, or might choose beat because they have heard phrases like that is hard to beat. However, the collocation accomplish a huge feat is the standard one in English. Paying attention to how words pair with verbs like accomplish helps in avoiding these errors.

Final Answer:
The correct word is feat, so the sentence should read you will accomplish a huge feat.
